Production of welding wire with ultrasonic removal of surface lubricant residues

An ultrasound device installed in the wire-drawing line permits the industrial production of welding wire with ultrasonic removal of lubricant residues from the surface, so as to improve wire performance. The welding wire produced in this way prevents disruption of electrical contact during welding and hence interruption of the arc, splashing of the metal, and other factors that impair weld-seam quality.
